JDY-22 sleep pattern description
Sleep pattern:Instructions:Functional description
Start wake-up:AT+STARTEN1:Mode 1:wake up call, users need sleep can be controlled by AT+SLEEP command, wake up can be awakened by PWRC pin low level.
Start sleep:AT+STARTENO:Mode 0:the power is very low under this mode. The connection calls the permeable transmission current at 900uA, disconnects the connection current below 200uA (can set the broadcast interval current to 30uA), this mode PWRC pin wake up, such as the serial port in 10 seconds without data or will not be connected to sleep automatically again into sleep
Common problem description
Problem:Answer to the question
1:how MCU disconnects the bluetooth connection in the connection state:In the connection state, the PWRC pin is pulled down, and the serial port sends AT+DISC to disconnect.
2:how much is the current when the module wakes up:All mode work current is not more than 1mA
3:How much data can be written to serial port once:No byte limit at 9600 baud rate
4:After the serial port is configured, do you need to restart it to take effect:It is recommended to restart the module when the parameters are set
5:How to test the depth of sleep current in the test module:It is recommended to test the current of VCC and GND pins
Default parameter configuration used in factory
Sequence:Function:Factory default parameters:Instructions
1:Serial port baud rate:9600:AT+BAUD4
2:Sleep pattern:Start wake-up:AT+STARTEN0
3:Broadcast name:JDY-21:AT+NAMHJDY-21
4:Broadcast interval:200MS:AT+ADVIN1
